| Bosch began lambda oxygen sensor production in 1976 and was a breakthrough for the introduction of a closed-loop control three-way catalytic converter. Today the lambda closed-loop control is common to most cars with gasoline engines. | |
| Bosch is developing system functions and components to support the efficient functioning of the NOx catalytic converters, including exhaust sensors based on the lambda oxygen sensor. | |

| For diesel commercial vehicles, we have the Denoxtronic® reduction agent metering system which is used with the Selective Catalytic Reduction (SCR) converter. | |
| For passenger cars we are developing a particulate filter designed to last the lifetime of the vehicle without need for maintenance or replacement. | |
